The small woolly bat is a little-known vesper bat, only slightly larger than Kitti's hog-nosed bat, one of the smallest mammals in the world. It weighs 2.5 to 4 g, with a head and body of 30–40 mm, a tail of 24–42 mm and a forearm of 27–31 mm. The fur is orange-brown on the back and paler brown below, and both the hair bases and the wing membrane are dark (Wikipedia, general species account).
